Over the past century or so, human activities have led to the rapid deterioration of the environment on Earth, with detrimental effects such as climate change and a rise in atmospheric CO2. Many scientists worldwide have thus been trying to devise new technologies and...
Ammonia (NH3) is a colorless, gaseous and water-soluble compound used in several sectors, including agriculture, the energy sector, and a variety of industries. For over a century, the main way of producing large quantities of ammonia has been via the Haber-Bosch...
Most existing lithium-ion batteries (LIBs) integrate graphite anodes, which have a capacity of approximately 350 milliamp hours (mAh) per gram. The capacity of silicon anodes is almost 10 times higher than that of their graphite counterparts (around 2,800 mAh per...
In recent years, 3-D printing has opened up interesting new possibilities for the large-scale production of electronic components, as well as of a variety of other objects. To this end, research teams worldwide have been trying to create materials and structures that...
Organic semiconductors, a class of carbon-based materials with optical and electronic properties, are now commonly used to fabricate a variety of devices, including solar cells, light-emitting diodes and field-effect transistors. These semiconducting materials can...
A team of researchers at Karlsruhe Institute of Technology (KIT) and Heidelberg University have recently introduced functional 3-D hetero-microstructures based on Poly (N-isopropylacrylamide) (pNIPAM) a polymer that responds to changes in temperature close to its...
